JACKSON, OF ATTLECBORO, MASSACHUSETTS,- ASSIGNOR T0 LEWIS R. SMITH RECEIVER FOR THE CHUSETTS APCO MOSSBERG CORPORATION, A CORPORATION OF MASSA- ENGINE HOOD ANTIRATTLING DEVICE 1 Application filedMay 15 1931. Serial No. 537,607.

My present invention relates to anti-rat'- tling devices, and more particularly to a novel and improved-anti-rattling device for use in connection with the engine hood and engine hood hold-down clamps of motor vehicles.

In many present day automobiles, the antirattling bumper comprises a rubber slug riveted to the side of the engine hood adjacent to the bottom thereof, and interposed beween the hood and the hood hold-down clamp. These bumpers are subjected to considerable wearand rough usage, and very frequently split,or become pulled away from the rivet during use. This results in a greatdeal of inconvenience to the motorist, requiring the removal of the rivet, as by shearing, and the replacing of an entire new bumper andrivet.

An important object of the present invention, therefore, resides in the provision of an anti-rattling device or bumper which may be readily attached in place of a worn or broken bumper, by being snapped over the original rivet.

Another object of theinvention resides in the provision of metallic means to take up and absorb the wear and vibrations between the rivet and the bumper.

A still further object of the invention resides in the provision of spring means to permit facile attachment of the device and also to prevent inadvertent removal thereof.

Other objects and features of the present invention, details of construction. combinations of parts, and advantages, will be hereinafter more fully pointed out, described and claimed.

Referring to the drawings, illustrating a preferred embodiment of the present invention,

Fig. 1 is a side elevation of my novel antirattling device in position;

Fig. 2 is a front elevation of the device;

Fig. 3 is a cross sectional view, on an enlarged scale, of the bumper positioned on the original rivet; and

Fig. 4 is a cross sectional view on the line 4-4 of Fig. 3. p

Referring now to the drawings,for a particular description of the invention, l designates a conventional automobile engine hood having the nded-beam e gesrad having clamp engaging ears, one of which is illustrated at 3 secured to the hood by the rivets 4. On the apron 5 is fixed a bracket 6 by rivets 7 this bracket carrying a pivot pin {5 8 on which is pivotally mounted the housing 9 Within which isslidable the stem 10 of the hood hold-down'clamp 11, a finger hold 12 being provided. The hold-down clamp ,llis

held in normal clamping position by means 1 of a coiled spring within the housing 9, but as this is standard constructionand constitutes no part of the present invention, the

same is not-illustrated or described in detail herein. a y

1 3 designates the rivet which holds the original bumpers to the engine hood, and this rivet is illustrated with my novel anti-rattling bumper positioned thereover.

My novel device comprises a bumper 14, :7

preferably of rubber, having a concaved outer face 15 with a central boss or plug 16. This bumper 14 is provided andhwith an undercut groove 18. Positioned in t e i also located in said groove is the flange 20 of with a recess 17 groove 18 is an annularwasher 19, and

a retainer 21. It-will be apparent, from a glance at the draw ngs, that the washer l9 and flange .20 are ofgreater diameter than the diameter of the recess 17, thus insuring 7 0 that thebumper 14 will not inadvertently be separated from either the flange. 20 or washer 19. Y

Interposed between the washer 19. and retainer 21 is a split spring ring 22, the normal diameter of this'split'ring being slightly lessthan the diameter of the head 23 of the rivet13. r

' It will also be apparent,-from a glance at the drawings, that .my" novel device is extremely simple to "apply,it being merely necessary to engage the head 23 ofsthe-rivet 13 with the spring ring 22, and eifect ai pressurethereagainst This will eifecta spread--5 ing or'opening of the spring ring 22" until said ringhas passed the edge or rim of the head 23, whereupon the spring ring 22 will return to normal contracted position, v at which time it will be behind the head 23, as

" The wall Ql is preferably of greater height.

than the normaldistance between the outer 3, the housing sonably wide limits without departing surface of the hood 1 and the flange when the device isli'n the position illustrated in Fig. 3. This will result in a'spring tension being exerted outwardly on the retainer 21 and ring:22,:maintaining the same in engage- .ment'with-the head 23 ;0f. the rivet 13.

When the device is attached and the holddown clamp 11 is in engagement with the ear 9 will bear across the face of the bumper 14, and will have .thereagainst partly because of'the material ofi'which the bumper is made,and partly because of the 'configuration of' said face.

Myjndvel. device is simple and economical to "manufacture, and very simple to. apply, requiring buta-s'light fraction of time to instalL The advantages-and benefits of my'antirattling device will be instantly apparent to those-skilledin-this-art, as well as to automob le owners,"'and sincel believe that this device is novel, "have claimed'the same broadly inthe present application.

fWhile 11' have necessarily described my present invention somewhat in detail, itwill be appreciated thatYI may vary the size, shape,and arrangement of parts,within reafrom the spiritofthe invention.
